Helping my cousin put his neat stuff together, and found that there are adapter rings to fit the bearing retainer to the bellhousing register. But of the two supplied, neither will work. So I suggested to get the correct one from keisler.
they told him you don't need one.
quicktime(lakewood ) said you dont need one.
Then his engine guy said you dont need one!!
I guess even though its of highest importance to check bellhousing alignment,, the trans doesnt have to register in the bore!!
The bolts must align it within a thousandths of an inch?
Or what am I missing? Please help a dumb mechanic.

Sounds like you need a cheap caliper to measure ID of hole and OD of transmission input bearing retainer size.

Then you can talk intelligently to them.

slide the rings over the input bearing retaining on the front of the transmission to determine if any fit. If not take the can (quicktime housing) and slide it over the input bearing retainer and determine is there is a bunch of slop. There should not be much.

Here are some instructions on dial indicating a bell housing for the Tremec's.

Bore Runout – Clutch Housing to Crank Shaft Centerline Alignment

When performing adjustments or repairs that involve removing the clutch housing, it will be necessary to check transmission mounting bore runout and squareness to the crankshaft when reassembling.

Note: If your engine has been line bored as part of a rebuild, this step can be omitted.
If you are using a Lakewood Scattershield, follow the manufacturer’s recommendations and instructions.

1.) Replace one flywheel to crankshaft bolt with a bolt that is about 3 inches long. Mount a dial indicator on this bolt with a “C” clamp. If you have a magnetic base for the dial indicator, this can be used in place of the bolt and “C” clamp arrangement.

2.) Rotate the engine clockwise, using a socket wrench on the vibration dampener bolt at the front of the crankshaft while noting dial indicator needle deflection. Bore out of round must not exceed .005 inch of maximum total indicator reading. (.0025 one-half total indicator reading)

3.) Excess bore run out must be corrected by installing correct size offset dowels. These dowels are available in three offset sizes and must be installed in pairs of the same size. Mopar Performance and Lakewood each sell these offset dowel pin kits. The offset dowels are in size of .007, .014 and .021 inch offsets.

4.) To illustrate the recommended correction procedure, assume the total indicator reading is .020 in a direction that indicates 2 o’clock on the engine block.

In this case, the clutch housing or scattershield is off crankshaft centerline by .010 inch (one-half of the total indicator reading) which is .008 inch greater than the allowable limit of .0025 (one-half total indicator reading).

In the case under consideration, installation of two (2) .007 inch offset dowels will bring the runout within the allowable limits of .0025 inch. .009 minus .007 inch offset dowels equals.002 inches of runout.

The amount of eccentricity of the dowel will produce a total indicator reading change of double the dowel eccentricity, therefore, select a pair of dowels to the nearest to one-half the total indicator runout.

For runout (total indicator reading) of .009 in. through .020 in., use a .007 in. offset dowel set.
For .021 through .034 in., use a .014 offset dowel set.
For .035 through .050 in., use a .021 inch dowel set.


To install the dowels, remove the clutch housing and old dowels from the rear face of the engine block.

Install both dowels with the slots parallel and aligned in the direction to correct the bore runout. The slot in the top of the dowel indicated the most of amount of offset. Make sure that both dowels are installed up to the shoulders of the offset.

5.) Install the clutch housing onto the engine block using the bolts that were removed. Tighten the bolts to the recommended torque specifications. 7/16 bolts tighten to 50 ft lbs. 3/8 bolts tighten to 30 ft. lbs.

6.) Recheck the runout by repeating steps 1 and 2. If the bore runout is within the acceptable limits, the clutch housing to engine alignment is complete.


Good luck and take your time!

Thank you my brothers!
I get the whole program... what threw me for a loop was the entire package came from keisler,, and they are telling my cousin that you don't need to have any of that stuff lined up.
Just throw the trans at it and burn rubber!!
So it comes down to my word VS the manufacturer. And I couldn't see myself being wrong on this, but did not want to appear as a moron. I'll leave that to others.

And again, they designed/manufactured/sold the products..not me.
They should now the dimensions better than anyone on earth.

The trans bearing retainer should be 4.850" and the hole in the bellhousing should be 4.91 without an adapter so it should be a sloppy fit without an adapter ring.

The problem is that they did NOT manufacture the products, and unless they measure every single unit that enters their shop there is a possibility of either manufacturing tolerance stackup or manufacturing error to mess you up.

That's why you need to measure the ID and the OD so they can get a handle on where the problem lies.

And of course, in an ideal world they'd check every single unit, but I can understand them not doing that.

Manufacturing processes are very very good and probably way less than 1% of the units they get don't meet specs. Or someone at the bellhousing place grabbed a wrong housing which is perfectly correct, just not for your application.

So you need to be an informed consumer and help them make it right. Unless I am badly mistaken, they don't want negative stories floating around the Web about their products. So they will do what is reasonable (to them) to get things put right.

Any high performance build has its lumps and bumps.

I agree. stuff is not always perfect.
But he made the effort to try and get it corrected, only to be told "you don't need the adapter ring". Right from Mr. K.
So had he put it together, and it screwed up, how helpful would they be at that point ? One can only speculate, luckily we will not be going down that road.
If business is going that well, might be time to hire a packaging Q.C. guy,,, or a competent tech line guy. As much as the bad tech info could have made our lives miserable, I will only give positive recommendations.

Keisler doesn't have a rep for having their act together in this regard. Why would they include rings in the kit if it wasn't needed?

The rings are included as a catch all for other applications. Ross, when he owned QuickTime, prior to selling quicktime had these pre-packaged with the required hardware to fit other transmissions that had bearing retainers smaller than the TKO. I believe its the T10 and the New Process 833. It's just extra parts and it created a bunch of phone calls. By the way, the tolerance on the bore should not be sloppy. The Tremec needs .005 TIR when dial indicating.
